:cp seems to only accept a single entry
scala> :cp /usr/lib/hadoop/*:/usr/lib/hadoop/lib/*:/usr/lib/hbase/*:/usr/lib/hbase/lib/*:
/home/sboesch/spark-master/lib_managed/jars/*:/home/sboesch/spark-master/lib_managed/bundles/*:
The path '/usr/lib/hadoop/*:/usr/lib/hadoop/lib/*:/usr/lib/hbase/*:/usr/lib/hbase/lib/*:/home/sboesch/spark-master/lib_managed/jars/*:/home/sboesch/spark-master/lib_managed/bundles/*:'
doesn't seem to exist.
Any thoughts on how to do this when already in the REPL. Yes I know how to set it up from outside the REPL :
CLASSPATH=/usr/lib/hadoop/*:/usr/lib/hadoop/lib/*:/usr/lib/hbase/*:/usr/lib/hbase/lib/*
:/home/sboesch/spark-master/lib_managed/jars/*:
/home/sboesch/spark-master/lib_managed/bundles/*: scala
EDIT It seems the intent were not clear. I am working on code in the REPL. Then have a new snippet of code that requires a few classpath entries. It is a ONE OFF affair: so I do not want to add to build.sbt or to the scala/lib dir , etc. I did not receive any answer really satisifying this use case, but awarded the best efforts anyways.
A quick and dirty approach, add a link from $SCALA_HOME/lib/ to a folder with additional jar files. Then from REPL you can import packages of interest.
